Neovim folds

• it is a built-in feature in Neovim; enables you to quickly navigate a long document by hiding them and opening them when you want

• some keybindings for managing folds

  Keymap	Description
  zf	Create a fold.
  zA	Toggle a fold recursively.
  zM	Close all folds.
  zR	Open all folds.
  zj	Move one fold down.
  zk	Move one fold up.

• while in insert mode, there are no folds under your cursor so you can see what you type

• while manually managing folds can be tedious, Neovim does have a way to automatically manage folds for you; this is dictated through the foldmethod variable; for more information for the following methods, see fold-${VALUE} with the Neovim help system

  • with manual value, no additional actions are done

  • with marker value, a fold will be created ala-HTML markers

  • with expr value, a fold will be managed through its fold level evaluated from foldexpr function; certain tools like nvim-treesitter takes advantage of this to arrange the code through its blocks, scope, etc.
